Abstract

A light for use in a light fixture includes a light source adapted to produce light in an area including the light and a connector configured for connection to the fixture. The light further includes a communication apparatus configured to generate one or more signals indicative of a presence of a person in the area, and a controller that is operative to control the light source in a normal mode in response to the one or more signals.

Claims

1. A light for use in a light fixture, comprising:

a light source adapted to produce light in an area including the light;

a connector configured for connection to the fixture;

a communication apparatus configured to generate one or more signals indicative of a presence of a person in the area; and

a controller operative to control the light source in a normal mode to produce a generally constant flux of light in response to the one or more signals.

2. The light of claim 1, wherein the light source includes at least one LED.

3. The light of claim 1, wherein the communication apparatus is at least one of an audio device or a camera.

4. The light of claim 3, wherein the audio device includes a speaker, further comprising:

a receiver configured to receive an audio signal, wherein the speaker is operable to output sound in response to the audio signal.

5. The light of claim 3, wherein the communication apparatus includes a memory operative to store a recording, and the audio device is operative to produce a sound corresponding to the recording.

6. The light of claim 1, further comprising:

a housing at least partially enclosing the light source and the communication apparatus, wherein the housing and the connector at least partially define a single package sized for use in the fixture.

7. The light of claim 6, wherein the housing includes a light transmitting portion and the light source includes multiple LEDs oriented to produce light through the light transmitting portion.

8. The light of claim 1, further comprising:

a battery electrically connected to at least one of the light source and the communication apparatus.

9. The light of claim 1, wherein the communications apparatus comprises:

a camera and a microphone; and

a transmitter to transmit at least one of audio captured by the microphone and an image captured by the camera.

10. An LED-based light for use in a light fixture, comprising:

at least one LED;

a communication apparatus configured to generate one or more signals;

a controller in communication with the at least one LED and the communication apparatus, the controller configured to identify the presence of a person in an area including the LED-based light based on the one or more signals and control the at least one LED to produce a generally constant flux of light based on the one or more signals;

a housing at least partially enclosing the at least on LED, the communication apparatus and the controller; and

a connector configured for connection to the fixture, wherein the housing and the connector at least partially define a single package sized for use in the fixture.

11. The LED-based light of claim 10, wherein:

the at least one LED is adapted to produce white light, and

the controller is configured to;

control the at least one LED to an off state; and

in response to identifying the presence of the person in the area, control the at least one LED to an on state so that the at least one LED produces a generally constant flux of white light.

12. The LED-based light of claim 11, wherein:

the one or more signals include at least one audio signal for the area, and

the controller is configured to identify the presence of a person in the area based on the at least one audio signal, wherein the identification includes at least one of;

determining that a sound over a predetermined volume is produced;

determining that a spike in sound to a predetermined level is greater than a level of normal background noise is produced;

determining that a series of sounds at similar frequency to footsteps are produced;

or

determining that a sound corresponding to human speech is produced.

13. The LED-based light of claim 11, wherein:

the one or more signals include at least one image signal for the area, and

the controller is configured to identify the presence of a person in the area based on the at least one audio signal, the identification including at least one of performing a facial recognition analysis or comparing successive images to detect a moving object.

14. The LED-based light of claim 10, further comprising:

a transmitter in communication with the communication apparatus for transmitting the one or more signals to a remote location.

15. The LED-based light of claim 10, wherein:

the at least one LED is adapted to produce white light, and

the controller is configured to control the at least one LED to an on state, identify an unoccupied state of an area including the LED-based light based on the one or more signals, and in response to identifying the unoccupied state of the area, intermittently control the at least one LED between the on state and an off state to give the appearance of activity in the area.

16. The LED-based light of claim 10, wherein the controller is configured to identify the presence of an emergency in an area including the LED-based light based on the one or more signals.

17. The LED-based light of claim 16, wherein the controller is configured to control the at least one LED to an off state, and in response to identifying the presence of the emergency in the area, control the at least one LED to an on state wherein the at least one LED produces a pattern of light.

18. The LED-based light of claim 16, wherein:

the communication apparatus includes a speaker, and

the controller is configured to control the speaker to produce a sound indicating the emergency in the area.

19. A light for use in light fixture, comprising:

a light source adapted to produce light in an area surrounding the light;

a communication apparatus configured to generate one or more signals indicative of a presence of a person in the area;

a connector configured for connection to the fixture;

a housing at least partially enclosing the light source and the communication apparatus, wherein the housing and the connector at least partially define a package sized for use in the fixture; and

a controller operative to control the light source in response to the one or more signals to produce a generally constant flux of light.

20. The light of claim 19, wherein the housing includes a light transmitting portion and the light source includes multiple LEDs oriented to produce light through the light transmitting portion.
